Abstract: AIR TO OIL, OR AIR TO OIL TO AIR HEAD EXCHANGER     ABSTRACT OF THE DISCLOSURE         The device consists of a stale air cell and a fresh air cell each containing a non-absorbent packing material bed with moist warm stale air passing upwardly through the bed of the stale air cell to be discharged externally  and  cold  dry  fresh  air  passing  upwardly through the bed of the fresh air cell to be discharged into the building in which the device is being used.  Oil which is relatively warm flows downwardly through the bed of the fresh air cell giving up heat to the cold dry fresh air passing upwardly therethrough.  This now rela-tively cold oil is then transferred to the upper side of the bed of the  stale air cell  and passes  downwardly therethrough picking up heat and moisture from the moist warm stale air passing upwardly through the bed.   The warm oil is collected in a reservoir at the base of the device and then pumped upwardly to the upper side of the upper cell.   Water which may condense out of the moist warm stale air is collected also in the reservoir and may be discharged externally when required.

Abstract: ABSTRACT OF THE DISCLOSURE           Sampled signal generating apparatus formed by variable line delay circuits and dot delay circuits receives a series of sampled signal of a composite color television signal  sampled in synchronism with a chrominance subcarrier at a frequency four times the chrominance subcarrier and generates simultaneously a sampled single at a specified sampled point for separating a luminance signal and a chrominance signal and sampled signals at four sampled points adjacent to the specified sampled point, namely, four sampled points on the upper, lower, right and left sides of the specified sampled point.  A comparing and determining circuit compares and determines a direction in which there is little change in the picture, based on the sampled signals at the adjacent sampled points.  Based on the results of the determination of the comparing and determining circuit, a selector selects and provides two sampled signals in a region where there is little change in the picture.  A separation filter separates a chrominance signal from the sampled signal at the specified sampled point using the two sampled signals provided from the selector. A subtractor subtracts the chrominance signal from the sampled signal at the specified sampled point so as to provide a luminance signal.

Abstract: PROCESS FOR FORMING UNUSUALLY STRONG JOINTS BETWEEN METALS AND CERAMICS BY BRAZING AT TEMPERATURES THAT DO NOT EXCEED 750°C       Abstract of the Disclosure This invention is a process for joining metals to ceramics to form very strong bonds using low brazing temperature, i.e., less than 750°C, and particularly for joining nodular cast iron to partially stabilized zirconia.  The process provides that the ceramic be coated with an active metal, such as titanium, that can form an intermetallic with a low melting point brazing alloy such as 60Ag-30Cu-10Sn.  The nodular cast iron is coated with a noncarbon containing metal, such as copper, to prevent carbon in the nodular cast iron from dissolving in the brazing alloy.  These coated surfaces can be brazed together with the brazing alloy between at less than 750°C to form a very strong joint.  An even stronger bond can be formed if a transition piece is used between the metal and ceramic.  It is preferred for the transition piece to have a coefficient of thermal expansion compatible with the coefficient of thermal expansion of the ceramic, such as titanium.

Abstract: ABSTRACT OF THE DISCLOSURE     A method for reducing the effect of narrowband jammers in communication between two stations utilising frequency hopping.  A new frequency is not selected merely with the aid of random number generation, but also with required knowledge of the radio communication environment affecting the selection.  The frequencies available for frequency hopping are stored with different status in a list.  The status of the different frequencies is deter-mined by quality measurement of the channel selected in a radio communication and by examining the status of the selected frequency in relation to the status of the re-maining frequencies.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to improvements in the manufacturing process for aluminum alloy die-cast cylinders, particularly for use in two stroke engines.  The cylinder is made in two die-cast alluminum parts, one first being the upper compression area and the second being the lower piston guiding area.  The housing in the upper portion and the lower portion are then turned followed by assembly of the two parts with maximum interference when hot or cold, thus obtaining a cylinder of the same conditions as the one moulded in shell or at low pressure.  This is then followed by the machining, hard chromium plating and inner finish with maximum precision and a surface quality of optimum fineness.  Good thermal conductivity values are thus obtained  which increases the performance of the cylinder when compared to the prior art devices.

Abstract: "PROCESS FOR PRODUCING A HYDROGEN-RICH GAS STREAM"                              ABSTRACT             A process for economically increasing the hydrogen purity of a hydrogen-rich gas stream from a reaction zone effluent comprising hydrogen and hydrocarbons is disclosed.  The multistep process essentially involves subjecting the effluent to a first phase separation at conventional conditions followed by recontacting a cooled portion of the vapor phase with a cooled 10 to 20% portion of the hydrocarbon liquid phase to achieve a second phase separation at a significantly lower temperature than the temperature used in the first separation.  The use of a 10 to 20% portion of the hydrocarbon phase recovered in the first phase separation instead of the entire amount results in a significant savings in utilities and capital costs for the refrigeration required to achieve the desired purification.

Abstract: Abstract:      Washing liquid is ejected and circulated through a suction pump and a hose from an outer tub and is sprinkled over clothes in a washing tub.  The amount of washing liquid supplied to the washing tub is set to be about three to eight times larger than that of the clothes to be washed in a weight ratio.  Washing is enhanced by sprinkling the washing liquid over the clothes.  By setting the amount of washing liquid supplied to the washing tub as small as about three to eight (3 to 8) times the weight of the clothes the clothes are prevented from floating on the washing liquid.  Accordingly it is possible to promote the friction and expansion and contraction action of the clothes and to increase the direct frictional effect caused by an agitator, with a consequent improvement in the wash-ing operation, i.e. the cleaning rate.

Abstract: ABSTRACT OF THE DISCLOSURE            An automatic address assignment system has a plurality of I/0 devices coupled to a bus.  Each device contains a unique machine-readable identifier which is used to select the device for address assignment.  The identifier is a binary bit string.  Each bit position in the bit string is selected by the host in a serial manner with the host specifying which binary value is being solicited.  All devices whose identifier digit matches the solicited value respond positively and remain in contention for address assignment.  The other devices will not respond and drop out of contention for address assignment until the sequence is restarted from the first bit.  After the bit sequence is completed, the address for that device is bused to the device, and the sequence is restarted from the first bit until all devices have been assigned an address.

Abstract: - ? -FIBER-OPTICAL PRESSURE DETECTOR     ABSTRACT OF THE DISCLOSURE An optical fiber disposed between a light source and a photodetector is subjected at a number of points, equispaced along its axis, to a transverse pressure caus-ing a significant attenuation of the transmitted luminous radiation.  The optimum spacing of the pressure points is a function of the radius of the fiber core and of the refractive indices of its core and its envelope.  These pressure points are formed by turns of a substantially incompressible helix which is wound around the fiber and which may be constituted by an internal or external rib of a surrounding flexible sheath of similarly incompressible material. The pressure may be applied by a piezoelectrical transducer and may be modulated by an electrical signal to be picked up by the photodetector.
